Oxidation of a cyclohexanone derivative using a Brevibacterium cyclohexanone monooxygenase

ABSTRACT

Two gene clusters have been isolated from an Brevibacterium sp HCU that encode the enzymes expected to convert cyclohexanol to adipic acid. Individual open reading frames (ORF&#39;s) on each gene cluster are useful for the production of intermediates in the adipic acid biosynthetic pathway or of related molecules. All the ORF&#39;s have been sequenced. Identification of gene function has been made on the basis of sequence comparison and biochemical analysis.

This is a Divisional application claiming priority to U.S. Ser. No. 09/504,358, filed Feb. 15, 2000, now U.S. Pat. No. 6,365,376 which claims the benefit of Provisional Application U.S. Ser. No. 60/120,702, filed Feb. 19, 1999.

FIELD OF THE INVENTION

The invention relates to the field of molecular biology and microbiology. More specifically, genes have been isolated from Brevibacterium sp HCU and sequences that encode for enzymes useful for production of intermediates in the adipic acid biosynthetic pathway or for the production of related molecules.

BACKGROUND OF THE INVENTION

Production of adipic acid in the U.S. was 1.96 billion pounds in 1997 with an estimated 2.0 billion pounds in 1998. Historically the demand for adipic acid has grown 2% per year and 1.5-2% is expected through the year 2002. Adipic acid consistently ranks as one of the top fifty chemicals produced domestically. Nearly 90% of domestic adipic acid is used to produce nylon-6,6. Other uses of adipic acid include production of lubricants and plasticizers, and as a food acidulant.

The dominant industrial process for synthesizing adipic acid employs initial air oxidation of cyclohexane to yield a mixture of cyclohexanone (ketone) and cyclohexanol (alcohol), which is designated KA (see for example U.S. Pat. No. 5,221,800). Hydrogenation of phenol to yield KA is also used commercially, although this process accounts for just 2% of all adipic acid production. KA produced via both methods is oxidized with nitric acid to produce adipic acid. Reduced nitrogen oxides including NO₂, NO, and N₂O are produced as by-products and are recycled back to nitric acid at varying levels.

Research has also focused on synthesis of adipic acid from alternative feedstocks. Significant attention has been directed at carbonylation of butadiene (U.S. Pat. No. 5,166,421). More recently, a method of dimerizing methyl acrylates was reported, opening up the possibility of adipic acid synthesis from C-3 feedstocks.

These processes are not entirely desirable due to their heavy reliance upon environmentally sensitive feedstocks, and their propensity to yield undesirable by-products. Non-synthetic, biological routes to adipic acid would be more advantageous to industry and beneficial to the environment.

A number of microbiological routes are known. Wildtype and mutant organisms have been shown to convert renewable feedstocks such as glucose and other hydrocarbons to adipic acid [Frost, John, Chem. Eng. (Rugby, Engl.) (1996), 611, 32-35; WO 9507996; Steinbuechel, AlexanderCLB Chem. Labor Biotech. (1995), 46(6), 277-8; Draths et al., ACS Symp. Ser. (1994), 577 (Benign by Design), 32-45; U.S. Pat. No. 4,400,468; JP 49043156 B4; and DE 2140133]. Similarly, organisms possessing nitrilase activity have been shown to convert nitriles to carboxylic acids including adipic acid [Petre et al., AU 669951; CA 2103616].

Additionally, wildtype organisms have been used to convert cyclohexane and cyclohexanol and other alcohols to adipic acid [JP 01023894 A2; Cho, Takeshi et al., Bio Ind. (1991), 8(10), 671-8; Horiguchi et al., JP 01023895 A2; JP 01023894 A2; JP 61128890 A; Hasegawa et al., Biosci., Biotechnol., Biochem. (1992), 56(8), 1319-20; Yoshizako et al., J. Ferment. Bioeng. (1989), 67(5), 335-8; Kim et al., Sanop Misaengmul Hakhoechi (1985), 13(1), 71-7; Donoghue et al., Eur. J. Biochem. (1975), 60(1), 1-7].

One enzymatic pathway for the conversion of cyclohexanol to adipic acid has been suggested as including the intermediates cyclohexanol, cyclohexanone, 2-hydroxycyclohexanone, ε-caprolactone, 6-hydroxycaproic acid, and adipic acid. Some specific enzyme activities in this pathway have been demonstrated, including cyclohexanol dehydrogenase, NADPH-linked cyclohexanone oxygenase, ε-caprolactone hydrolase, and NAD (NADP)-linked 6-hydroxycaproic acid dehydrogenase (Tanaka et al., Hakko Kogaku Kaishi (1977), 55(2), 62-7). An alternate enzymatic pathway has been postulated to comprise cyclohexanol→cyclohexanone→1-oxa-2-oxocycloheptane→6-hydroxyhexanoate→6-oxohexanoate→adipate [Donoghue et al., Eur. J. Biochem. (1975), 60(1), 1-7]. The literature is silent on the specific gene sequences encoding the cyclohexanol to adipic acid pathway, with the exception of the monoxygenase, responsible for the conversion of cyclohexanone to caprolactone, [Chen,et al., J. Bacteriol., 170, 781-789 (1988)].

The problem to be solved, therefore is to provide a synthesis route for adipic acid which not only avoids reliance on environmentally sensitive starting materials but also makes efficient use of inexpensive, renewable resources. It would further be desirable to provide a synthesis route for adipic acid which avoids the need for significant energy inputs and which minimizes the formation of toxic by-products.

Applicants have solved the stated problem by identifying, isolating and cloning a two unique monooxygenase genes, a hydrolase gene, a hydroxycaproate dehydrogenase gene, a cyclohexanol dehydrogenase gene and a gene encoding an acyl-CoA dehydrogenase, all implicated in the adipic acid biosynthetic pathway.

As used herein, an “isolated nucleic acid fragment” is a polymer of RNA or DNA that is single- or double-stranded, optionally containing synthetic, non-natural or altered nucleotide bases. An isolated nucleic acid fragment in the form of a polymer of DNA may be comprised of one or more segments of cDNA, genomic DNA or synthetic DNA.

The term “adipic acid synthesizing protein” means the gene product of any of the sequences set forth in SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, and SEQ ID NO:25.

As used herein, “substantially similar” refers to nucleic acid fragments wherein changes in one or more nucleotide bases results in substitution of one or more amino acids, but do not affect the functional properties of the protein encoded by the DNA sequence. “Substantially similar” also refers to nucleic acid fragments wherein changes in one or more nucleotide bases does not affect the ability of the nucleic acid fragment to mediate alteration of gene expression by antisense or co-suppression technology. “Substantially similar” also refers to modifications of the nucleic acid fragments of the instant invention such as deletion or insertion of one or more nucleotide bases that do not substantially affect the functional properties of the resulting transcript. It is therefore understood that the invention encompasses more than the specific exemplary sequences.

For example, it is well known in the art that alterations in a gene which result in the production of a chemically equivalent amino acid at a given site, but do not effect the functional properties of the encoded protein are common. Thus, a codon for the amino acid alanine, a hydrophobic amino acid, may be substituted by a codon encoding another less hydrophobic residue (such as glycine) or a more hydrophobic residue (such as valine, leucine, or isoleucine). Similarly, changes which result in substitution of one negatively charged residue for another (such as aspartic acid for glutamic acid) or one positively charged residue for another (such as lysine for arginine) can also be expected to produce a functionally equivalent product. Nucleotide changes which result in alteration of the N-terminal and C-terminal portions of the protein molecule would also not be expected to alter the activity of the protein. Each of the proposed modifications is well within the routine skill in the art, as is determination of retention of biological activity of the encoded products. Moreover, the skilled artisan recognizes that substantially similar sequences encompassed by this invention are also defined by their ability to hybridize, under stringent conditions (0.1×SSC, 0.1% SDS, 65° C. and washed with 2×SSC, 0.1% SDS followed by 0.1×SSC, 0.1% SDS), with the sequences exemplified herein. Preferred substantially similar nucleic acid fragments of the instant invention are those nucleic acid fragments whose DNA sequences are at least 80% identical to the DNA sequence of the nucleic acid fragments reported herein. More preferred nucleic acid fragments are at least 90% identical to the DNA sequence of the nucleic acid fragments reported herein. Most preferred are nucleic acid fragments that are at least 95% identical to the DNA sequence of the nucleic acid fragments reported herein.

A nucleic acid molecule is “hybridizable” to another nucleic acid molecule, such as a cDNA, genomic DNA, or RNA, when a single stranded form of the nucleic acid molecule can anneal to the other nucleic acid molecule under the appropriate conditions of temperature and solution ionic strength. Hybridization and washing conditions are well known and exemplified in Sambrook, J., Fritsch, E. F. and Maniatis, T. Molecular Cloning: A Laboratory Manual, Second Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor (1989), particularly Chapter 11 and Table 11.1 therein (entirely incorporated herein by reference). The conditions of temperature and ionic strength determine the “stringency” of the hybridization. For preliminary screening for homologous nucleic acids, low stringency hybridization conditions, corresponding to a T_(m) of 55°, can be used, e.g., 5×SSC, 0.1% SDS, 0.25% milk, and no formamide; or 30% formamide, 5×SSC, 0.5% SDS. Moderate stringency hybridization conditions correspond to a higher T_(m), e.g., 40% formamide, with 5×or 6×SSC. Hybridization requires that the two nucleic acids contain complementary sequences, although depending on the stringency of the hybridization, mismatches between bases are possible. The appropriate stringency for hybridizing nucleic acids depends on the length of the nucleic acids and the degree of complementation, variables well known in the art. The greater the degree of similarity or homology between two nucleotide sequences, the greater the value of Tm for hybrids of nucleic acids having those sequences. The relative stability (corresponding to higher T_(m)) of nucleic acid hybridizations decreases in the following order: RNA:RNA, DNA:RNA, DNA:DNA. For hybrids of greater than 100 nucleotides in length, equations for calculating Tm have been derived (see Sambrook et al., supra, 9.50-9.51). For hybridizations with shorter nucleic acids, i.e., oligonucleotides, the position of mismatches becomes more important, and the length of the oligonucleotide determines its specificity (see Sambrook et al., supra, 11.7-11.8). In one embodiment the length for a hybridizable nucleic acid is at least about 10 nucleotides. Preferable a minimum length for a hybridizable nucleic acid is at least about 15 nucleotides; more preferably at least about 20 nucleotides; and most preferably the length is at least 30 nucleotides. Furthermore, the skilled artisan will recognize that the temperature and wash solution salt concentration may be adjusted as necessary according to factors such as length of the probe.

A “substantial portion” of an amino acid or nucleotide sequence comprising enough of the amino acid sequence of a polypeptide or the nucleotide sequence of a gene to putatively identify that polypeptide or gene, either by manual evaluation of the sequence by one skilled in the art, or by computer-automated sequence comparison and identification using algorithms such as BLAST (Basic Local Alignment Search Tool; Altschul, S. F., et al., (1993) J. Mol. Biol. 215:403-410; see also www.ncbi.nlm.nih.gov/BLAST/). In general, a sequence of ten or more contiguous amino acids or thirty or more nucleotides is necessary in order to putatively identify a polypeptide or nucleic acid sequence as homologous to a known protein or gene. Moreover, with respect to nucleotide sequences, gene specific oligonucleotide probes comprising 20-30 contiguous nucleotides may be used in sequence-dependent methods of gene identification (e.g., Southern hybridization) and isolation (e.g., in situ hybridization of bacterial colonies or bacteriophage plaques). In addition, short oligonucleotides of 12-15 bases may be used as amplification primers in PCR in order to obtain a particular nucleic acid fragment comprising the primers. Accordingly, a “substantial portion” of a nucleotide sequence comprises enough of the sequence to specifically identify and/or isolate a nucleic acid fragment comprising the sequence. The instant specification teaches partial or complete amino acid and nucleotide sequences encoding one or more particular fungal proteins. The skilled artisan, having the benefit of the sequences as reported herein, may now use all or a substantial portion of the disclosed sequences for purposes known to those skilled in this art. Accordingly, the instant invention comprises the complete sequences as reported in the accompanying Sequence Listing, as well as substantial portions of those sequences as defined above.

The term “complementary” is used to describe the relationship between nucleotide bases that are capable to hybridizing to one another. For example, with respect to DNA, adenosine is complementary to thymine and cytosine is complementary to guanine. Accordingly, the instant invention also includes isolated nucleic acid fragments that are complementary to the complete sequences as reported in the accompanying Sequence Listing as well as those substantially similar nucleic acid sequences.

The term “percent identity”, as known in the art, is a relationship between two or more polypeptide sequences or two or more polynucleotide sequences, as determined by comparing the sequences. In the art, “identity” also means the degree of sequence relatedness between polypeptide or polynucleotide sequences, as the case may be, as determined by the match between strings of such sequences. “Identity” and “similarity” can be readily calculated by known methods, including but not limited to those described in: Computational Molecular Biology (Lesk, A. M., ed.) Oxford University Press, New York (1988); Biocomputing: Informatics and Genome Projects (Smith, D. W., ed.) Academic Press, New York (1993); Computer Analysis of Sequence Data, Part I (Griffin, A. M., and Griffin, H. G., eds.) Humana Press, New Jersey (1994); Sequence Analysis in Molecular Biology (von Heinje, G., ed.) Academic Press (1987); and Sequence Analysis Primer (Gribskov, M. and Devereux, J., eds.) Stockton Press, New York (1991). Preferred methods to determine identity are designed to give the largest match between the sequences tested. Methods to determine identity and similarity are codified in publicly available computer programs. Preferred computer program methods to determine identity and similarity between two sequences include, but are not limited to, the GCG Pileup program found in the GCG program package, as used in the instant invention, using the Needleman and Wunsch algorithm with their standard default values of gap creation penalty=12 and gap extension penalty=4 (Devereux et al., Nucleic Acids Res. 12:387-395 (1984)), BLASTP, BLASTN, and FASTA (Pearson et al., Proc. Natl. Acad. Sci. U.S.A. 85:2444-2448 (1988). The BLAST X program is publicly available from NCBI and other sources (BLAST Manual, Altschul et al., Natl. Cent. Biotechnol. Inf., Natl. Library Med. (NCBI NLM) NIH, Bethesda, Md. 20894; Altschul et al., J. Mol. Biol. 215:403-410 (1990)). Another preferred method to determine percent identity, is by the method of DNASTAR protein alignment protocol using the Jotun-Hein algorithm (Hein et al., Methods Enzymol. 183:626-645 (1990)). Default parameters for the Jotun-Hein method for alignments are: for multiple alignments, gap penalty=11, gap length penalty=3; for pairwise alignments ktuple=6. As an illustration, by a polynucleotide having a nucleotide sequence having at least, for example, 95% “identity” to a reference nucleotide sequence of SEQ ID NO:1 it is intended that the nucleotide sequence of the polynucleotide is identical to the reference sequence except that the polynucleotide sequence may include up to five point mutations per each 100 nucleotides of the reference nucleotide sequence of SEQ ID NO:1. In other words, to obtain a polynucleotide having a nucleotide sequence at least 95% identical to a reference nucleotide sequence, up to 5% of the nucleotides in the reference sequence may be deleted or substituted with another nucleotide, or a number of nucleotides up to 5% of the total nucleotides in the reference sequence may be inserted into the reference sequence. These mutations of the reference sequence may occur at the 5′ or 3′ terminal positions of the reference nucleotide sequence or anywhere between those terminal positions, interspersed either individually among nucleotides in the reference sequence or in one or more contiguous groups within the reference sequence. Analogously, by a polypeptide having an amino acid sequence having at least, for example, 95% identity to a reference amino acid sequence of SEQ ID NO:2 is intended that the amino acid sequence of the polypeptide is identical to the reference sequence except that the polypeptide sequence may include up to five amino acid alterations per each 100 amino acids of the reference amino acid of SEQ ID NO:2. In other words, to obtain a polypeptide having an amino acid sequence at least 95% identical to a reference amino acid sequence, up to 5% of the amino acid residues in the reference sequence may be deleted or substituted with another amino acid, or a number of amino acids up to 5% of the total amino acid residues in the reference sequence may be inserted into the reference sequence. These alterations of the reference sequence may occur at the amino or carboxy terminal positions of the reference amino acid sequence or anywhere between those terminal positions, interspersed either individually among residues in the reference sequence or in one or more contiguous groups within the reference sequence.

“Codon degeneracy” refers to divergence in the genetic code permitting variation of the nucleotide sequence without effecting the amino acid sequence of an encoded polypeptide. Accordingly, the instant invention relates to any nucleic acid fragment that encodes all or a substantial portion of the amino acid sequence encoding the bacterial adipic acid synthesizing proteins as set forth in SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:14, SEQ ID NO:18, SEQ ID NO:22, SEQ ID NO:24, and SEQ ID NO:26. The skilled artisan is well aware of the “codon-bias” exhibited by a specific host cell in usage of nucleotide codons to specify a given amino acid. Therefore, when synthesizing a gene for improved expression in a host cell, it is desirable to design the gene such that its frequency of codon usage approaches the frequency of preferred codon usage of the host cell.

“Synthetic genes” can be assembled from oligonucleotide building blocks that are chemically synthesized using procedures known to those skilled in the art. These building blocks are ligated and annealed to form gene segments which are then enzymatically assembled to construct the entire gene. “Chemically synthesized”, as related to a sequence of DNA, means that the component nucleotides were assembled in vitro. Manual chemical synthesis of DNA may be accomplished using well established procedures, or automated chemical synthesis can be performed using one of a number of commercially available machines. Accordingly, the genes can be tailored for optimal gene expression based on optimization of nucleotide sequence to reflect the codon bias of the host cell. The skilled artisan appreciates the likelihood of successful gene expression if codon usage is biased towards those codons favored by the host. Determination of preferred codons can be based on a survey of genes derived from the host cell where sequence information is available.

“Gene” refers to a nucleic acid fragment that expresses a specific protein, including regulatory sequences preceding (5′ non-coding sequences) and following (3′ non-coding sequences) the coding sequence. “Native gene” refers to a gene as found in nature with its own regulatory sequences. “Chimeric gene” refers any gene that is not a native gene, comprising regulatory and coding sequences that are not found together in nature. Accordingly, a chimeric gene may comprise regulatory sequences and coding sequences that are derived from different sources, or regulatory sequences and coding sequences derived from the same source, but arranged in a manner different than that found in nature. “Endogenous gene” refers to a native gene in its natural location in the genome of an organism. A “foreign” gene refers to a gene not normally found in the host organism, but that is introduced into the host organism by gene transfer. Foreign genes can comprise native genes inserted into a non-native organism, or chimeric genes. A “transgene” is a gene that has been introduced into the genome by a transformation procedure.

“Coding sequence” refers to a DNA sequence that codes for a specific amino acid sequence. “Suitable regulatory sequences” refer to nucleotide sequences located upstream (5′ non-coding sequences), within, or downstream (3′ non-coding sequences) of a coding sequence, and which influence the transcription, RNA processing or stability, or translation of the associated coding sequence. Regulatory sequences may include promoters, translation leader sequences, introns, and polyadenylation recognition sequences.

“Promoter” refers to a DNA sequence capable of controlling the expression of a coding sequence or functional RNA. In general, a coding sequence is located 3′ to a promoter sequence. Promoters may be derived in their entirety from a native gene, or be composed of different elements derived from different promoters found in nature, or even comprise synthetic DNA segments. It is understood by those skilled in the art that different promoters may direct the expression of a gene in different tissues or cell types, or at different stages of development, or in response to different environmental conditions. Promoters which cause a gene to be expressed in most cell types at most times are commonly referred to as “constitutive promoters”. It is further recognized that since in most cases the exact boundaries of regulatory sequences have not been completely defined, DNA fragments of different lengths may have identical promoter activity.

“RNA transcript” refers to the product resulting from RNA polymerase-catalyzed transcription of a DNA sequence. When the RNA transcript is a perfect complementary copy of the DNA sequence, it is referred to as the primary transcript or it may be a RNA sequence derived from posttranscriptional processing of the primary transcript and is referred to as the mature RNA. “Messenger RNA (mRNA)” refers to the RNA that is without introns and that can be translated into protein by the cell. “cDNA” refers to a double-stranded DNA that is complementary to and derived from mRNA. “Sense” RNA refers to RNA transcript that includes the mRNA and so can be translated into protein by the cell. “Antisense RNA” refers to a RNA transcript that is complementary to all or part of a target primary transcript or mRNA and that blocks the expression of a target gene (U.S. Pat. No. 5,107,065). The complementarity of an antisense RNA may be with any part of the specific gene transcript, i.e., at the 5′ non-coding sequence, 3′ non-coding sequence, introns, or the coding sequence. “Functional RNA” refers to antisense RNA, ribozyme RNA, or other RNA that is not translated yet has an effect on cellular processes.

The term “operably linked” refers to the association of nucleic acid sequences on a single nucleic acid fragment so that the function of one is affected by the other. For example, a promoter is operably linked with a coding sequence when it is capable of affecting the expression of that coding sequence (i.e., that the coding sequence is under the transcriptional control of the promoter). Coding sequences can be operably linked to regulatory sequences in sense or antisense orientation.

The term “expression”, as used herein, refers to the transcription and stable accumulation of sense (MRNA) or antisense RNA derived from the nucleic acid fragment of the invention. Expression may also refer to translation of mRNA into a polypeptide.

“Mature” protein refers to a post-translationally processed polypeptide; i.e., one from which any pre- or propeptides present in the primary translation product have been removed. “Precursor” protein refers to the primary product of translation of mRNA; i.e., with pre- and propeptides still present. Pre- and propeptides may be but are not limited to intracellular localization signals.

“Transformation” refers to the transfer of a nucleic acid fragment into the genome of a host organism, resulting in genetically stable inheritance. Host organisms containing the transformed nucleic acid fragments are referred to as “transgenic” or “recombinant” or “transformed” organisms.

The terms “plasmid”, “vector” and “cassette” refer to an extra chromosomal element often carrying genes which are not part of the central metabolism of the cell, and usually in the form of circular double-stranded DNA molecules. Such elements may be autonomously replicating sequences, genome integrating sequences, phage or nucleotide sequences, linear or circular, of a single- or double-stranded DNA or RNA, derived from any source, in which a number of nucleotide sequences have been joined or recombined into a unique construction which is capable of introducing a promoter fragment and DNA sequence for a selected gene product along with appropriate 3′ untranslated sequence into a cell. “Transformation cassette” refers to a specific vector containing a foreign gene and having elements in addition to the foreign gene that facilitate transformation of a particular host cell. “Expression cassette” refers to a specific vector containing a foreign gene and having elements in addition to the foreign gene that allow for enhanced expression of that gene in a foreign host.

Standard recombinant DNA and molecular cloning techniques used here are well known in the art and are described by Sambrook, J., Fritsch, E. F. and Maniatis, T., Molecular Cloning: A Laboratory Manual, Second Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (1989) (hereinafter “Maniatis”); and by Silhavy, T. J., Bennan, M. L. and Enquist, L. W., Experiments with Gene Fusions, Cold Spring Harbor Laboratory Cold Press Spring Harbor, N.Y. (1984); and by Ausubel, F. M. et al., Current Protocols in Molecular Biology, published by Greene Publishing Assoc. and Wiley-Interscience (1987).

The nucleic acid fragments of the instant invention may be used to isolate cDNAs and genes encoding homologous enzymes from the same or other bacterial species. Isolation of homologous genes using sequence-dependent protocols is well known in the art. Examples of sequence-dependent protocols include, but are not limited to, methods of nucleic acid hybridization, and methods of DNA and RNA amplification as exemplified by various uses of nucleic acid amplification technologies (e.g., polymerase chain reaction, ligase chain reaction).

For example, genes encoding similar enzymes to those of the instant adipic acid pathway, either as cDNAs or genomic DNAs, could be isolated directly by using all or a portion of the instant nucleic acid fragments as DNA hybridization probes to screen libraries from any desired bacteria using methodology well known to those skilled in the art. Specific oligonucleotide probes based upon the instant nucleic acid sequences can be designed and synthesized by methods known in the art (Maniatis). Moreover, the entire sequences can be used directly to synthesize DNA probes by methods known to the skilled artisan such as random primers DNA labeling, nick translation, or end-labeling techniques, or RNA probes using available in vitro transcription systems. In addition, specific primers can be designed and used to amplify a part of or full-length of the instant sequences. The resulting amplification products can be labeled directly during amplification reactions or labeled after amplification reactions, and used as probes to isolate full length cDNA or genomic fragments under conditions of appropriate stringency.

In addition, two short segments of the instant ORF's may be used in polymerase chain reaction protocols to amplify longer nucleic acid fragments encoding homologous genes from DNA or RNA. The polymerase chain reaction may also be performed on a library of cloned nucleic acid fragments wherein the sequence of one primer is derived from the instant nucleic acid fragments, and the sequence of the other primer takes advantage of the presence of the polyadenylic acid tracts to the 3′ end of the MRNA precursor encoding bacterial genes. Alternatively, the second primer sequence may be based upon sequences derived from the cloning vector. For example, the skilled artisan can follow the RACE protocol (Frohman et al., PNAS USA 85:8998 (1988)) to generate cDNAs by using PCR to amplify copies of the region between a single point in the transcript and the 3′ or 5′ end. Primers oriented in the 3′ and 5′ directions can be designed from the instant sequences. Using commercially available 3′ RACE or 5′ RACE systems (BRL), specific 3′ or 5° cDNA fragments can be isolated (Ohara et al., PNAS USA 86:5673 (1989); Loh et al., Science 243:217 (1989)).

Availability of the instant nucleotide and deduced amino acid sequences facilitates immunological screening cDNA expression libraries. Synthetic peptides representing portions of the instant amino acid sequences may be synthesized. These peptides can be used to immunize animals to produce polyclonal or monoclonal antibodies with specificity for peptides or proteins comprising the amino acid sequences. These antibodies can be then be used to screen cDNA expression libraries to isolate full-length CDNA clones of interest (Lerner, R. A. Adv. Immunol. 36:1 (1984); Maniatis).

The enzymes and gene products of the instant ORF's may be produced in heterologous host cells, particularly in the cells of microbial hosts, and can be used to prepare antibodies to the resulting proteins by methods well known to those skilled in the art. The antibodies are useful for detecting the proteins in situ in cells or in vitro in cell extracts. Preferred heterologous host cells for production of the instant enzymes are microbial hosts. Microbial expression systems and expression vectors containing regulatory sequences that direct high level expression of foreign proteins are well known to those skilled in the art. Any of these could be used to construct chimeric genes for production of the any of the gene products of the instant ORF's. These chimeric genes could then be introduced into appropriate microorganisms via transformation to provide high level expression of the enzymes.

Additionally, chimeric genes will be effective in altering the properties of the host bacteria. It is expected, for example, that introduction of chimeric genes encoding one or more of the ORF's 1.2, 1.3, 1.4, 1.6, 1.7, 2.2 and 2.4 under the control of the appropriate promoters, into a host cell comprising at least one copy of these genes will demonstrate the ability to produce various intermediates in the adipic acid biosynthetic pathway. For example, the appropriately regulated ORF 1.2, would be expected to express an enzyme capable of converting ε-caprolactone to 6-hydroxy hexanoic acid (FIG. 1). Similarly, ORF 2.2 or ORF 1.4 would be expected to express an enzyme capable of converting 6-hydroxy hexanoic acid to 6-aldehyde hexanoic acid (FIG. 1). Additionally ORF 1.6 or ORF 1.7 would, be expected to express an enzyme capable of converting cyclohexanol to cyclohexanone (FIG. 1). Finally, expression of both GC-1 (SEQ ID NO:15) or GC-2 (SEQ ID NO:16) in a single recombinant organism will be expected to effect the conversion of cyclohexanol to adipic acid in a transformed host (FIG. 2).

ORF 1.3 or ORF 2.4 encode the Brevibacterium sp HCU monooxygenase. Applicant has demonstrated that this monooxygenase, although useful for the conversion of cyclohexanone to ε-caprolactone, has substrate specificity for a variety of other single ring compounds, including, but not limited to cyclobutanone, cyclopentanone, 2-methylcyclopentanone, 2-methylcyclohexanone, cyclohex-2-ene-1-one, 2-(cyclohex-1-enyl)cyclohexanone, 1,2-cyclohexanedione, 1,3-cyclohexanedione, and 1,4-cyclohexanedione (see Table 2). It is contemplated that the instant monooxygenases would be useful in the bioconversion of any molecule containing a complete oxidized or derivatized cyclohexanone substructure, such as for example progesterone or 2-amino hydroxycaproate.

It is further contemplated that the open reading frames showing high homology to bacterial regulatory elements may in fact be useful in constructing various expression vectors. For example, ORF's 1.1 and 2.3 each appear to encode a transcriptional regulator. It is contemplated that these ORF's may be used in regulatable expression vectors for for HiGC Gram positive bacteria (a group including, but not limited to, the genera Brevibacterium, Corynebacterium, Mycobacterium, Rhodococcus, Arthrobacter, Nocardia, Streptomyces, Actinomyces). For example, such vectors may include the gene encoding the transcription regulator (whether repressor or activator) as well as promoter derived from the upstream sequence of GC-1 or GC-2. Induction of transcription of genes cloned downstream of the promoter sequence would be induced by the addition in the growth medium of the molecule that induces either cluster. Likely inducers of GC-1 or GC-2 expression would be cyclohexanol or cyclohexanone or products of their oxidation.

Vectors or cassettes useful for the transformation of suitable host cells are well known in the art. Typically the vector or cassette contains sequences directing transcription and translation of the relevant gene, a selectable marker, and sequences allowing autonomous replication or chromosomal integration. Suitable vectors comprise a region 5′ of the gene which harbors transcriptional initiation controls and a region 3′ of the DNA fragment which controls transcriptional termination. It is most preferred when both control regions are derived from genes homologous to the transformed host cell, although it is to be understood that such control regions need not be derived from the genes native to the specific species chosen as a production host.

Initiation control regions or promoters, which are useful to drive expression of the instant ORF's in the desired host cell are numerous and familiar to those skilled in the art. Virtually any promoter capable of driving these genes is suitable for the present invention including but not limited to CYC1, HIS3, GAL1, GAL10, ADH1, PGK, PHO5, GAPDH, ADC1, TRP1, URA3, LEU2, ENO, TPI (useful for expression in Saccharomyces); AOX1 (useful for expression in Pichia); and lac, trp, lP_(L), lP_(R), T7, tac, and trc (useful for expression in Escherichia coli).

Termination control regions may also be derived from various genes native to the preferred hosts. Optionally, a termination site may be unnecessary, however, it is most preferred if included.

Description of the Preferred Embodiments

The present invention relates to the isolation of genes encoding enzymes useful for the conversion of cyclohexanol to adipic acid, and for the production of enzymatic intermediates in the adipic acid biosynthetic pathway. The relevant genes were isolated from a Brevibacterium sp. which was cultured from an industrial waste stream. Colonies that had the ability to grow on halophilic minimal medium in the presence of cyclohexanone were selected for further study. Taxonomic identification of the Brevibacterium sp HCU was accomplished on the basis of 16s rDNA analysis. Using RT-PCR, two gene clusters (GC-1 and GC-2) were identified and cloned. All open reading frames (ORF's) residing on both gene clusters were sequenced. The organization of the ORF's as well as the putative identification of gene function is shown in FIG. 2. The ORF's encoding two cyclohexanone monooxygenases were cloned into expression hosts and expression of the genes was confirmed on the basis of gel electrophoresis. GC-MS analysis confirmed the activity of the expressed Cyclohexanone monoooxygenase proteins in vitro as well as expressed in the E. coli host.

In similar fashion, ORF's 2.2 and 1.4 were isolated and cloned into an E. coli expression host for expressions studies. GC-MS analysis confirmed that 6-hydroxy hexanoic promotes the reduction of NAD into NADH, suggesting that both transformants obtained the ability to convert 6-hydroxy hexanoic acid to the corresponding aldehyde. This data provided evidence that ORF's 2.2 and 1.4 encode a 6-hydroxy hexanoic acid dehydrogenase activity.

The method for the identification of GC-1 and GC-2 as well as the relevant open reading frames is a modified RT-PCT protocol, and is based on the concept of mRNA differential display (McClelland et al., U.S. Pat. No. 5,487,985; Liang, et al., Nucleic Acids Res. (1994), 22(25), 5763-4; Liang et al., Nucleic Acids Res. (1993), 21(14), 3269-75; Welsh et al., Nucleic Acids Res. (1992), 20 (19), 4965-70). The method was particularly adaptable to the instant isolation of the monooxygenase genes as it relies on the inducibility of the gene or pathway message.

The instant method is a technique that compares the mRNAs sampled by arbitrary RT-PCR amplification between control and induced cells. For the analysis of bacterial genomes, typically only a small set of primers is used to generate many bands which are then analyzed by long high resolution sequencing gels. Applicant has modified this approach using a larger set of about 81 primers analyzed on relatively short polyacrylamide urea gels (15 cm long and 1.5 mm thick). Due to their thickness and small length these gels do not have the resolution of sequencing gels and faint bands are difficult to detect. Each primer generates a RAPD pattern of an average of ten DNA fragments. Theoretically, a set of 81 primers should generate about 800 independent bands.

The basic protocol involves 6 steps which follow growth of the cells and total RNA extraction. The steps are: (i) arbitrarily primed reverse transcription and PCR amplification, (ii) separation and visualization of PCR products, (iii) elution, reamplification and cloning of differentially expressed DNA fragments, (iv) sequencing of clones (v) assembly of clones in contigs and sequence analysis; and (vi) identification of induced metabolic pathways

Arbitrarily primed reverse transcription and PCR amplification were performed with the commercial enzyme kit from Gibco-BRL “Superscript One-Step RT-PCR System” which provides buffers, the reverse transcriptase and the Taq polymerase in a single tube. The reaction mix contains 0.4 mM of each dNTP and 2.4 mM MgSO₄ in addition to other components.

The primers used were a collection of 81 primers with the sequence 5′-CGGAGCAGATCGAVVVV(SEQ ID NO:38) where VVVV represent all the combinations of the three bases A, G and C at the last four positions of the 3′-end. The 5′ end sequence was designed as to have minimal homology towards both orientations of the 16S rDNA sequences from many organisms with widespread phylogenetic position in order to minimize non specific amplification of these abundant and stable RNA species.

The 81 primers were pre-aliquoted on five 96 well PCR plates. In each plate, each primer was placed in two adjacent positions as indicated below.

A1 A1 A2 A2 A3 A3 A4 A4 A5 A5 A6 A6 A7 A7 A8 A8 A9 A9 A10 A10 A11 A11 A12 A12 A13 A13 A14 A14 A15 A15 A16 A16 A17 A17 A18 A18 A19 A19 A20 A20 A21 A21 A22 A22 A23 A23 A24 A24 A25 A25 A26 A26 A27 A27 A28 A28 A29 A29 A30 A30 A31 A31 A32 A32 A33 A33 A34 A34 A35 A35 A36 A36 A37 A37 A38 A3g A39 A39 A40 A40 A41 A41 A42 A42 A43 A43 A44 A44 A45 A45 A46 A46 A47 A47 A48 A48

Typical RT-PCT was then performed using standard protocols well known in the art.

Separation and visualization of PCR products was carried out as follows: 5 μl out each 25 μl RT-PCR reaction were analyzed on precuts acrylamide gels (Excell gels Pharmacia Biotech). PCR products from control and Induced RNA generated from the same primers were analyzed side by side. The gels were stained with the Plus One DNA silver staining Kit (Pharmacia Biotech) to visualized the PCR Fragments then rinsed extensively with distilled water for one hour to remove the acetic acid used in the last step of the staining procedure. DNA fragments from control and induced lanes generated from the same primers were compared. Bands present in the induced lane but not in the control lane were excised with a scalpel.

Elution, reamplification and cloning of differentially expressed DNA fragments was carried out as follows. Each band excised from the gel was placed in a tube containing 50 μl of 10 mM KCl and 10 mM Tris-HCl pH 8.3 and heated to 95° C. for 1 hr to allow some of DNA to diffuse out of the gel. Serial dilutions of the eluate (1/10) were used as template for a new PCR reaction using the following reactions: Mg Acetate (4 mM), dNTPs (0.2 mM), Taq polymerase buffer (Perkin Elmer), oligonucleotide primer (0.2 μM). The primer used for each rearnplification was the one that had generated the DNA pattern.

Each reamplified fragment was cloned into the blue/white cloning vector pCR2.1-Topo (Invitrogen).

Four to eight clones from the cloning of each differentially expressed band were submitted to sequencing using the universal forward. Inserts that did not yield a complete sequence where sequenced on the other strand with the reverse universal primer.

The nucleotide sequences obtained where trimmed for vector, primer and low quality sequences, and aligned using the Sequencher program (Gene Code Corporation). The sequences of the assembled contigs were then compared to protein and nucleic acid sequence databases using the BLAST alignment program (BLAST Manual, Altschul et al., Natl. Cent. Biotechnol. Inf., Natl. Library Med. (NCBI NLM) NIH, Bethesda, Md. 20894; Altschul et al., J. Mol. Biol. 215:403-410 (1990)).

Once all contigs were assembled, the number of bands having yielded clones included in the contig was plotted. Many contigs were composed of the sequence of distinct identical clones from the cloning of a single band. Such contigs may represent false positives, i.e., PCR bands not really differentially expressed. In other cases the PCR bands may represent genes actually induced but having been sampled by only one primer in the experiment. Some contigs were generated from the alignment of DNA sequences from bands amplified by distinct primers.

The present invention is further defined in the following Examples. It should be understood that these Examples, while indicating preferred embodiments of the invention, are given by way of illustration only. From the above discussion and these Examples, one skilled in the art can ascertain the essential characteristics of this invention, and without departing from the spirit and scope thereof, can make various changes and modifications of the invention to adapt it to various usages and conditions.

Enzymatic Assays

The cyclohexanone monooxygenase activity of each overexpressed enzyme was assayed spectrophotometrically at 340 nm by monitoring the oxidation of NADPH. In a spectrophotometer cuvette containing 50 mM Tris-HCl, 50 mM K Acetate pH7 at 30° C. NADPH 0.3 mM and 20-50 μg of homogenous monooxygenase the reaction was initiated by the addition of 1 mM of cyclohexanone. Substrate specificity of each enzyme was tested with other cyclic ketones added at 0.1 or 0.5 mM.

Confirmation of the oxidation of cyclohexanone into caprolactone was determined by GC-Mass Spectrometry on a HP 5890 Gas Chromatograph with HP 5971 mass selective detector equipped with a HP-1 capillary column (Hewlett Packard). Prior to analysis, samples were acidified to pH 3 by HCl, extracted by dichloromethane three times, dried with MgSO4 and filtered.

Example 1 Isolation of a Cyclohexanone Degrading Brevibacterium sp. HCU

Selection for a halotolerant bacterium degrading cyclohexanol and cyclohexanone was performed on agar plates of a halophilic minimal medium (Per 1: Agar 15 g, NaCl 100 g, MgSO4 10 g, KCl 2 g, NH4Cl 1 g, KH2PO4 50 mg, FeSO4 2 mg, Tris HCl 8 g, pH 7) containing traces of yeast extract and casaminoacids (0.005% each) and incubated under vapors of cyclohexanone at 30° C. The inoculum was a resuspension of sludge from industrial wastewater treatment plant. After two weeks, beige colonies were observed and streaked to purity on the same plates under the same conditions.

Taxonomic identification was performed by PCR amplification of 16S rDNA using primers corresponding to conserved regions of the 16S rDNA molecule (Amann).

These primers were:

5′-GAGTTTGATCCTGGCTCAG-3′ SEQ ID NO:28

5′-ATGGCTGTCGTCAGCTCGTG-3′ SEQ ID NO:37

The complete 16s DNA sequence of the isolated Brevibacterium sp. HCU was found to be unique and is shown as SEQ ID NO:49.

Induction of the Cyclohexanone Degradation Pathway

Inducibility of the cyclohexanone pathway was tested by respirometry in low salt medium. One colony of strain HCU was inoculated in 300 ml of S12 mineral medium (50 mM KHPO₄ buffer (pH 7.0), 10 mM (NH4)₂SO₄, 2 mM MgCl₂, 0.7 mM CaCl₂, 50 uM MnCl₂, 1 μM FeCl₃, 1 μM ZnCl₃, 1.72 μM CuSO₄, 2.53 μM CoCl₂, 2.42 μM Na₂MoO₂, and 0.0001% FeSO₄) containing 0.005% yeast extract. The culture was then split in two flasks which received respectively 10 mM Acetate and 10 mM cyclohexanone. Each flask was incubated for six hrs at 30° C. to allow for the induction of the cyclohexanone degradation genes. The cultures were then chilled on iced, harvested by centrifugation and washed three times with ice cold S 12 medium lacking traces of yeast extract. Cells were finally resuspended to an absorption of 2.0 at 600 nm and kept on ice until assayed.

Half a ml of each culture was placed in a water jacketed respirometry cell equipped with an oxygen electrode (Yellow Spring Instruments Co., Yellow spring, Ohio) and containing 5 ml of air saturated S12 medium at 30° C. After establishing the baseline respiration for each of the cell suspensions, acetate or cyclohexanone were added to a final concentration of 0.02% and the rate of O₂ consumption was further monitored.

Example 2 Identification of Genes Involved in the Oxidation of Cyclohexanone

Identification of genes involved in the oxidation of cyclohexanone made use of the fact that this oxidation pathway is inducible. The mRNA populations of a control culture and a cyclohexanone-induced culture were compared using a technique based on the random amplification of DNA fragments by reverse transcription followed by PCR.

Isolation of Total Cellular RNA

The cyclohexanone oxidation pathway was induced by addition of 0.1% cyclohexanone in one of two “split” cultures of Brevibacterium HCU grown as described in the GENERAL METHODS. Each 10 ml culture was chilled rapidly in an ice/water bath and transferred to a 15 ml tube. Cells were collected by centrifugation for 2 min. at 12,000×g in a rotor chilled to −4° C. The supernatants were discarded, the pellets resuspended in 0.7 ml of ice cold solution of 1% SDS and 100 mM Na acetate at pH 5 and transferred to a 2 ml tube containing 0.7 ml of aqueous phenol pH 5 and 0.3 ml of 0.5 mm zirconia beads (Biospec Products, Bartlesville, Okla.). The tubes were placed in a bead beater (Biospec Products, Bartlesville, Okla.) and disrupted at 2400 beats per-min. for two min.

Following the disruption of the cells, the liquid phases of the tubes were transferred to new microfuge tubes and the phases separated by centrifugation for 3 min. at 15,000×g. The aqueous phase containing total RNA was extracted twice more with phenol at pH 5 and twice with a mixture of phenol/chloroform/isoamyl alcohol pH 7.5 until a precipitate was no longer visible at the phenol/water interface. Nucleic acids were then recovered from the aqueous phase by ethanol precipitation with three volumes of ethanol and the pellet resuspended in 0.5 ml of diethyl pyrocarbonate (DEPC) treated water. DNA was digested by 6 units of RNAse-free DNAse (Boehringer Mannheim, Indianapolis, Ind.) for 1 hr at 37° C. The total RNA solution was then extracted twice with phenol/chloroform/isoamyl alcohol pH 7.5, recovered by ethanol precipitation and resuspended in 1 ml of DEPC treated water to an approximate concentration of 0.5 mg per ml.

RT-PCR Oligonucleotide Set

A set of 81 primers was designed with the sequence CGGAGCAGATCGAVVVV (SEQ ID NO:38) where VVVV represent all the combinations of the three bases A, G and C at the last four positions of the 3′-end.

Generation of RAPDs Patterns from Arbitrarily Reverse-Transcribed Total RNA

Arbitrarily amplified DNA fragments were generated from the total RNA of control and induced cells by following the protocol described by Wong K. K. et al., (Proc Natl Acad Sci USA. 91:639 (1994)). A series of parallel reverse transcription/PCR amplification experiments each using one oligonucleotide per reaction were performed on the total RNA from the control and induced cells. Briefly, 50 μl reverse transcription reactions were performed on 20-100 ng of total RNA using the 100 u Moloney Murine Leukemia Virus (MMLV) reverse transcriptase (Promega, Madison, Wis.) with 0.5 mM of each dNTP and 1 mM for each oligonucleotide primer. Reactions were prepared on ice and incubated at 37° C. for 1 hr.

Five μl from each RT reaction were then used as template in a 50 μl PCR reaction containing the same primer used for the RT reaction (0.25 μM), dNTPs (0.2 mM each), Mg Acetate (4 mM) and 2.5 u of the Taq DNA polymerase Stoffel fragment (Perkin Elmer, Foster City, Calif.). The following temperature program was used: 94° C. (5 min.), 40° C. (5 min.), 72° C. (5 min.) for 1 cycle followed by 40 cycles of: 94° C. (1 min.), 60° C. (1 min.), 72° C. (5 min.).

RAPD fragments were separated by electrophoresis on acrylamide gels (15 cm×15 cm×1.5 mm, 6% acrylamide, 29/1 acryl/bisacrylamide, 100 mM Tris, 90 mM borate, 1 mM EDTA pH 8.3). Five μl from each PCR reaction were analyzed, running side by side the reactions from the control and the induced RNA for each primer. Electrophoresis was performed at 1 V/cm. DNA fragment were visualized by silver staining using the Plus One® DNA silver staining kit in the Hoefer automated gel stainer (Amersham Pharmacia Biotech, Piscataway, N.J.).

Reamplification of the Differentially Expressed DNA

Stained gels were rinsed extensively for one hr with distilled water. Bands generated from the RNA of cyclohexanone induced cells but absent in the reaction from the RNA of control cells were excised from the gel and placed in a tube containing 50 μl of 10 mM KCl and 10 mM Tris-HCl pH 8.3 and heated to 95° C. for 1 hr to allow some of the DNA to diffuse out of the gel. Serial dilutions of the eluate over a 200 fold range were used as template for a new PCR reaction using the taq polymerase. The primer used for each reamplification (0.25 μM) was the one that had generated the pattern.

Each reamplified fragment was cloned into the blue/white cloning vector pCR2.1 (Invitrogen, San Diego, Calif.) and sequenced using the universal forward and reverse primers.

Example 3 Cloning, Sequencing and Identification of ORF's on GC-1 and GC-2

Kilobase-long DNA fragments extending the sequences fragments identified by differential display were generated by “Out-PCR”, a PCR technique using an arbitrary primer in addition to a sequence specific primer.

Genomic DNA was used as template in 10 separate 50 μl PCR reactions using the long range rTth XL DNA polymerase (Perkin-Elmer, Foster City, Calif.) and one of 10 arbitrary primers described above. The reaction included the rTth XL buffer provided by the manufacturer, 1.2 mM Mg Acetate, 0.2 mM of each dNTP, genomic DNA (10-100 ng) and 1 unit of rTth XL repolymerase. Annealing was performed at 45° C. to allow arbitrary priming of the genomic DNA and the DNA replication was extended for 15 min. at 72° C. At that point each reaction was split in two. One of the two tubes was kept unchanged and used as a control while the other tube received a specific primer corresponding to the end sequence of a differentially expressed fragment to be extended and directed towards the outside of the fragment. For example to extend the sequence of the first monooxygenase, two primers were designed one diverging from the 5′ end of the differentially displayed fragment #1 (5′-GATCCACCAAGTTCCTCC-3′, [SEQ ID NO:39]) and one diverging from 3′ end of the differentially displayed fragment #3 (5′-CCCGGTAAATCACGTGAGTACCACG-3′, [SEQ ID NO:40]). Thirty additional PCR cycles were performed and the two reactions were analyzed side by side by agarose electrophoresis. For about one fifth of the arbitrary primers used, one or several additional bands were present in the sample having received the specific primer. These bands were excised from the gel , melted in 0.5 ml H2O and used as template in a set of new PCR reactions that included rTth XL buffer, 1.2 mM Mg Acetate, 0.2 mM of each dNTP, 0.4 μM of primers, 1/1000 dilution of the melted slice 1 μl and 1 unit of rTth XL polymerase.

For each reamplification, two control reactions were performed in order to test that the reamplification of the band of interest. Each reaction omitted either the arbitrary or the specific primer.

The Reaction Components

The DNA fragments that fulfilled that condition were sequenced using the specific primer. The subset of DNA fragment with sequence overlap with the differentially expressed fragment to be extended were further sequenced either by “primer walking” or “shotgun cloning” of a partial MobI digest in pCR2.1 (Invitrogen, San Diego, Calif.).

To rule out the creation of PCR artifacts, overlapping DNA fragments 2-3 kb long were reamplified from chromosomal DNA using primers derived from the assembled sequence.

ORF's contained on GC-1 and GC-2 were identified by conducting BLAST (Basic Local Alignment Search Tool; Altschul, S. F., et al., (1993) J. Mol. Biol. 215:403-410; see also www.ncbi.nlm.nih.gov/BLAST/) searches for similarity to sequences contained in the BLAST “nr” database (comprising all non-redundant GenBank CDS translations, sequences derived from the 3-dimensional structure Brookhaven Protein Data Bank, SWISS-PROT protein sequence database, EMBL, and DDBJ databases). The sequences obtained were analyzed for similarity to all publicly available DNA sequences contained in the “nr” database using the BLASTN algorithm provided by the National Center for Biotechnology Information (NCBI). The DNA sequences were translated in all reading frames and compared for similarity to all publicly available protein sequences contained in the “nr” database using the BLASTX algorithm (Gish, W. and States, D. J. (1993) Nature Genetics 3:266-272) provided by the NCBI.

The sequence comparisons based on BLASTX analysis against the “nr” database are given below in Table 1 using Xnr BLAST algorithm.

Example 4 Expression of Monooxygenases in E. coli

The monooxygenase genes were cloned in the multiple cloning site of the N-terminal His6 expression vector pQE30 (Qiagen). Each gene was amplified by PCR from chromosomal DNA using primers corresponding to the ends of the gene and engineered to introduce a restriction site (underlined) not present in the gene. The oligonucleotides 5′-GAAAGATCGAGGATCCATGCCAATTACACAAC-3′ (SEQ ID NO:41) and 5′-TCGAGCAAGCTTGGCTGCAA-3′ (SEQ ID NO:42) were used for the cluster 1 monooxygenase gene and 5′-TCGAAGGAGGAGGCATGCATGACGTCAACC-3′ (SEQ ID NO:43) and 5′-CAGCAGGGACAAGCTTAGACTCGACA-3′(SEQ ID NO:44) for the cluster 2 monooxygenase gene.

The resulting plasmids (pPCB1 and pPCB2) were introduced into E. coli strain DH10B containing a pACYC 184 (tet^(R)) derivative with the lacIQ gene cloned in the EcoRI site of the chloramphenicol acetyl transferase gene to provide a tighter repression of the gene to be expressed.

Expression of the His6-tagged proteins was done by growing the cells carrying the expression plasmids in 1 l of Luria-Bertani broth (Miller 1972) containing Ampicillin (100 μg/ml) and tetracyclin (10 μg/ml) at 28° C. Riboflavin (1 μg/ml) was also added to the medium since both monooxygenases are flavoproteins. When the absortion reached 0.5 at 600 nm, 1 mM isopropy-thio-b-galactoside (IPTG) was added to the culture. Cells were harvested 1.5 hr later, resuspended in 2 ml of 300 mM NaCl 5% glycerol 20 mM Tris-HCl pH 8.0 (Buffer A) containing 10 mM EDTA and 100 μg lysozyme and disrupted by three freeze/thaw cycles. Nucleic acids were digested by addition of MgCl2 (20 mM) RNAseA and DNAse I (10 μg each). The particulate fraction was removed by centrifugation at 14,000 RPM and the supernatant was mixed for 1 hr at 4° C. with 100 μl of a metal chelation agarose (Ni-NTA Superflow Qiagen, Valencia, Calif.) saturated with Ni(II) and equilibrated Buffer A containing 5 mM imidazole. The resin was washed bathchwise with 10 ml each of Buffer A containing 5, 10, 15, 20, 40, 80, 150 and 300 mM respectively. The bound proteins were eluted between 80 and 150 mM imidazole. Eluted proteins were concentrated by ultrafiltration with a Centricon device (cut off 10,000 Da, Amicon) and the buffer replaced by Buffer A. Homogeneity of the overexpressed proteins is shown in FIG. 3, which show a gel electrophoresis separation of proteins from control E. coli (lane 1), E. coli expressing ORF 1.3 (lane 2) and E. coli expressing ORF 2.4 (lane 3).

Each monooxygenase oxidized cyclohexanone as measured spectrophoto-metrically by monitoring the oxidation of NADPH at 340 nm. For example, monooxygenase activity from the expression of ORF 1.3 is shown in FIG. 4. No activity was observed when NADPH was replaced by NADH. The product of the cyclohexanone oxidation was confirmed to be caprolactone by GC-MS analysis. Monooxygenase 1 and 2 have different substrate specificity relative to the number of carbon atoms, the oxidation or the substitution of the ring. The specificity of each enzyme for various cyclic ketones is shown in Table 2.

Example 5 Conversion of Cyclohexanone into Caprolactone by Cell Suspentions

Twenty ml cultures of E. coli strains carrying plasmids pPCB1 and pPCB2 that express the monooxygenase ORF 1.3 and ORF 2.4 respectively were grown at 30° C. in LB medium containing Ampicillin (100 μg/ml) and tetracyclin (10 μg/ml). When the absorbance reached 0.1 at 600 nm, 1 mM IPTG was added to the culture to induce the monooxygenases. After 1 hr, the cultures were chilled and washed twice with M9 mineral medium (Sambrook, J., Fritsch, E. F. and Maniatis, T. Molecular Cloning: A Laboratory Manual, Second Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor (1989)) and resuspended in 2 ml of the same medium containing 0.2% glucose and 100 ppm of cyclohexanone. After one hr the cells were removed from the culture by centrifugation and supernatant was analyzed by GC-MS as described in the General Methods. The GC-MS analysis indicated the disappearance of cyclohexanone and the appearance of caprolactone. When the rate of cyclohexanone oxidation was plotted as % cyclohexanone remaining vs. time it was seen that all cyclohexanone was oxidized in about 75 min (FIG. 5).

Example 6 Expression and Activity of Hydroxycaproate Dehydrogenase by E. Coli Expressing ORF 2.2

ORF 2.2 encoding a member of the long chain Zn-dependent dehydrogenase was amplified by PCR using the primers 5′-ATGAAAGCATTCGCAATGAAGGCA-3′ (SEQ ID NO:45) and 5′-CCGCACGGAACCCGTCTCC-3′ (SEQ ID NO:48) and cloned in the expression vector pTrc/His-Topo to yield plasmid pPCB7.

E. coli strains carrying plasmid pPCB7 that express ORF 2.2 or plasmid pPCB1 that express ORF 1.3, here used as a negative control for dehydrogenase expression, were grown at 25° C. in LB medium containing Ampicillin (100 μg/ml). When the absorbance reached 0.1 at 600 nm, 1 mM IPTG was added to the cultures to induce the dehydrogenase or the monooxygenase 1.

After 3 hr, the cells were harvested, resuspended in 1 ml of 100 mM Tris Buffer pH 8 containing 10 mM EDTA, treated for 30 min with lyzozyme (10 μg/ml) at 0° C. and lysed by three freeze/thaw cycles. Brevibacterium sp. HCU was grown in LB at 30° C. until it reached 1.0 at 600 nm. Cells were harvested, resuspended in S12 medium containing 0.005% yeast extract and 0.1% cyclohexanone and incubated at 30° C. for six hr to induce the cyclohexanone degradation pathway. At that points cells were harvested and lysed by overnight treatment with lyzozyme (100 μg/ml) at 0° C. and freeze thaw cycles. Extracts of the two E. coli strains and the Brevibacterium were analyzed at 4° C. by non-denaturing electrophoresis on 12% acrylamide gels (PAGEr™, FMC Rockland, Me.) at 10 V/cm. Protein bands with hydroxycaproate dehydrogenase activity were detected by activity stain using containing 3-(4,5-dimethylthiazolyl)-2,5-diphenyl tetrazolium bromide (MTT) (25 μg/ml), phenazine metosulfate (2.5 μg/ml), NAD (0.15 mM) and hydroxycaproate (1 mM), ammonium sulfate (30 mM) in 100 mM Tris Buffer pH 8.5 (Johnson, E. A. and Lin, E. C., J. Bacteriol 169:2050 (1987)). A blue precipitate band indicated the catalysis of NAD reduction by hydroxycaproate and the subsequent reduction of the tetrazolium dye by NADH via the phenazine metosulfate.

As seen in FIG. 6 (gel electrophoresis protein separation) the E. coli strain expressing ORF 2.2 (lane 2) expressed a hydroxycaproate dehydrogenase that comigrated with that of Brevibacterium sp. HCU (lane 3). This band was not observed in the control E. coli strain (lane 1). The enzyme expressed by pPCB7, and the commigrating enzyme from Brevibacterium sp. HCU also oxidized cyclohexanol and catalyzed the first step of the oxidation of cyclohexanol into adipic acid as show in FIG. 7. FIG. 7 shows two gel strips illustrating protein separation from E. coli expressing ORF 2.2 (lanes 1 and 3) and Brevibacterium HCU (lanes 2 and 4).

An identical experiment was performed for the Fe-dependent dehydrogenase gene ORF 1.4. It was amplified from chromosomal DNA using the primers 5′-ATGGAGTCGCACAACGAAAACAC-3′ (SEQ ID:47) and 5′-GCTCACTCGGCCCACCAGC-3′ (SEQ ID:48), cloned in the expression vector pTRc-His2 Topo and expressed in E. coli. Cell extracts of E. coli cells expressing ORF 1.4 as well as of cells not expressing it were analyzed by acrylimide gel electrophoresis on PhastTM Gels (Pharmacia Biotech, Piscataway, N.J.) and hydroxycaproate dehydrogenase activity was detected by the activity stain described above and shown in FIG. 8. The gel shown in FIG. 8 shows E. coli expressing ORF 1.4 (lanes 1, and 2) ORF 2.2 (lanes 3 and 4), the E. coli control (lane 5) and E. coli expressing ORF 1.3 (lane 6).
